\subsection{{\tt{norm}}: Point Location Normalization\label{s:toys-norm}}

This module normalizes point coordinates so that all points lie within the unit square $[0{\ldots}1]{\times}[0{\ldots}1]$.

{\inputspec}

\begin{description}
\item[{\tt{points}}:]
	a vector of point locations.
\end{description}

{\outputspec}

\begin{description}
\item[{\tt{points}}:]
	a vector of normalized point locations.
\end{description}

If $x_{min}$ and $x_{max}$ are the minimum and maximum $x$ coordinate values in the input vector,
then the normalization equation is:
\[	x_{i}^{\prime} = \frac{x_i - x_{min}}{x_{max} - x_{min}}	\]
$y$ coordinates are normalized in the same fashion.
